Has anyone tried using ARC motors as a brushless upgrade?

If I remember correctly the stock motors are 37g, I'm not sure of the other specs.
Specs for the ARC's are:

Either
ARC-20-27-80
• ARC 80 watt brushless motor
• Kv: 4500, io: 0.57A (8V), Rm: 100 (mOhms)
• Weight: 29g
• 2mm Shaft
• Dimensions: 20mm x 27mm (w/o shaft)
Or
ARC-20-34-110
• ARC 110 watt brushless motor
• Kv: 3100, io: 0.46A (8V), Rm: 120 (mOhms)
• Weight: 39g
• 2mm Shaft
• Dimensions: 20mm x 34mm (w/o shaft)

They can be seen here http://www.lightflightrc.com/

Is there a way to connect a brushless controller to the 4 in 1? or convert it somehow?

Cheers,

Giles
